Virtual Drive development

Hello to everyone.

I want to develop a virtual drive that will behave similarily with a normal
disk, but to be mounted from a file in the original file system. The format
of the file will be also developed by me.

Can someone give me some directions? What to study, what is the
architechture of such virtual drive? Do I need a new device driver
developed? Do I need a File System Filter Driver? etc.

I mention that I have DDK and IFS ready available as well as MSDN Library
documentation.

Thanks in advance for any help!

Have a look at VMware, it's format of virtual disks & mount utility.

I am not sure I understand. I want to develop using C and DDK/IFS a virtual
drive... I have looked at vmware many times but I don't follow your point.
What should I observe at vmware? Can you be more specific?

Thanks!

Check with StorageCraft http://www.storagecraft.com/ I know Jamey Kirby did
one of these. Beaware that there is a stolen copy of this at
http://www.acc.umu.se/~bosse/ the asshole slapped on a GNU license on
Jamey's work.

The VSPORT product suite provides you such a driver as a sample.

Maybe the RAMDISK sample in the NT 4.0 DDK can be of some help
(...\src\storage\disk\ramdisk).

IIRC, the RAMDISK source code is *very* small and simple. Now if you
would just write to a file instead of using memory...

However, I have no clue if the programming model used by RAMDISK is
still accurate for W2K/XP.
